Abstract (en)
Multi-component aqueous primer compositions (APC) comprising a component (K1) containing water and epoxy resin(s) (A), a component (K2) containing polyamine(s) (B) and if necessary other component(s), in which the APC contains carbon black, epoxysilane(s) (ES), epoxysiloxane(s) (ESx), amino-silane(s) (AS), aminosiloxane(s) (Asx) and/or mercaptosilane(s) (MS), with the proviso that, if ES and/or ESx is present, it is not in the same component as any AS and/or ASx. Independent claims are also included for (1) an adhesive bonding or sealing method involving making APC as above, applying it to a substrate (S1), drying in air, applying an adhesive or sealant and contacting with a second substrate (S2), or by carrying out the same process but applying the adhesive or sealant to S2 instead of S1, or by applying the adhesive or sealant between S1 and S2 (which may consist of the same or different materials) (2) articles manufactured by a process involving this method.
Abstract (de)
Die vorliegende Erfindung betrifft zwei- oder mehrkomponentige wässrige Epoxidharz-Primerzusammensetzungen bestehend aus einer ersten Komponente, einer zweiten und allenfalls weiterer Komponente. Die erste Komponente enthält mindestens Wasser und ein Epoxidharz. Die zweite Komponente enthält mindestens ein Polyamin. Weiterhin enthält die Zusammensetzung Russ und/oder Epoxysilan ES und/oder Epoxysiloxan ESx und/oder ein Aminosilan AS und/oder ein Aminosiloxan ASx und/oder Mercaptosilan MS. Die wässrige Epoxidharz-Primerzusammensetzungen führen zu verbesserten Haftung von feuchtigkeitshärtenden Polyurethan-Kleb- oder-Dichtstoffen auf diversen Untergründen.
